Just keep in mind that 10 cents/can adds up
I remember my freshmen year there was a group of kids living in some huge Victorian house that had been modified to have like 7 bedrooms and had about 9-10 people living there... As a house rule, no one threw away cans, and all cans went into a "general fund" to cover utility bills and shared essentials like paper towels, toilet paper, cleaning supplies, etc.
They would throw these huge parties since it wasn't hard to get 50 people there with just a few phone calls... They would get a small keg occasionally, but usually it was BYOB... They were pretty good at getting people to leave their cans there... So at the end of the night, they would have tons of beer cans at a dime per...
After one epic weekend, they went to Econo Foods to return their bounty for the weekend... Total came to just over $120... Now I don't know how valid this is, but supposedly because of the high amount that Econo had to pay out on a regular basis, they were told never to come back with cans again... Not sure if that was just a legend or not, but I do know that they did fund a good chunk of their utility bills and whatnot through cans...
